在分子和形态分析的基础上，我们描述了两个新的日本松露种：块菌属(Tuber Iryudaense)和毛块菌属(Tuber Tomentosum)。这两种植物通过覆盖在肉瘤表面的赭色被绒毛的菌丝体明显地与其他块茎物种区分开来。块茎Iryudaense有单孢子囊，每个包含一个大的(68-97 x 51-80亩m)，红棕色的子囊孢子；这些显微特征类似于中国近缘种，T.calosporum，T.Giantosporum，T.less rum，T.monosporum和T.sinomonosporum。块茎毛状菌每个子囊形成1~4个子囊孢子，其颜色与大孢子菌和管状菌的子囊孢子相似，但它们的孢子比毛蒜子囊菌的大得多(27-×26-55亩)。基于核糖体内转录间隔区和部分28S nuc rDNA序列的分子系统发育分析支持这两个物种在大孢子菌群中的不同。
We describe two new Japanese truffle species, Tuber iryudaense and Tuber tomentosum, based on molecular and morphological analyses. Both species are clearly distinguishable from other Tuber species by the ocher tomentose mycelium covering the ascoma surfaces. Tuber iryudaense has one-spored asci that each contain a large (68-97 x 51-80 mu m), reddish-brown ascospore; these microscopic characters are similar to those of closely related Chinese species, T. calosporum, T. gigantosporum, T. glabrum, T. monosporum, and T. sinomonosporum. Tuber tomentosum forms one to four ascospores per ascus with a reddish-brown color similar to that of ascospores of T. macrosporum and T. canaliculatum, although their spores are much larger than those of T. tomentosum (27-64 x 26-55 mu m). Molecular phylogenetic analyses based on ribosomal internal transcribed spacer and partial 28S nuc rDNA sequences support that both species are distinct within the Macrosporum group.
